Centrality dependence (expressed in terms of average number of participants) of prompt \jpsi \RAA measured by ALICE in \PbPb collisions at \snn = 5.02 TeV in the transverse momentum interval 1.5 $<$ \pt $<$ 10 \GeVc. Results are compared with the BT model by Zhuang {\it et al.} . Error bars and boxes represent statistical and uncorrelated systematic uncertainties, respectively. Shaded bands represent model uncertainties. The global uncertainty is shown around unity.
